IN TERNAIJ-COMBUSTION ENGINE Specification of Letters Patent.

Patented Feb. 6, 1917.

Application filed July 15, 1915. Serial No. 40, I03.

To all whom it may concern:

Be it known that I, LEONARD B. Sraunr, a citizen of the United States, residingat auwatosa, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in "internal- Combustion Engines, of which the following isa full, clean and exact specification.

This'invention relates to internal combustion engines. and in particular to improved means for supporting the magneto and it actuating gears, and a driving pulley upon a part of the engine structure comprising a single bracketmember carrying a stud upon 'Wl110h a pulley and a magneto actuating gear are journaled, a base member to which a magneto is secured, and an internal bearing box member forming a part of one of the bearings in which the crank shaft of the englue is journalod.

The ob'ect of the invention is to eliminate parts an simplify the construction of "the engine," thereby e 'ecting a material reduc tion incest.

2 I attain this object by means of the mech' anism illustrated in the accompanying drawings, in whic igure 1 is a top plan view of an internal combustion engine having my'invention emtii bodied in its construction;

Fig. 2 is a side elevation of part of Fig. 1; Fig. 3 is a side view of Figi2; 'Fig. 4 is a vertical section of part of Fig. 2, along line A-B, and designed to 15 the manner of mounting one of the power 'tramnnittinggears and its pulley; and

Fig. 5 is a sectional view along the same-- line of Fig. 2, showing the magneto operat:

, mg pinions. 60 9 same reference characters designate like parts throughout the several views.

1 represents the engine frame mounted upon a supporting base 2, including a power 6 cylinder 3, 11. connecting rod 4, and crank aft 5 journaled in bearing boxes 6, hav ing their lower half box? integral with the frame 1, and their upper half box 8 separable therefrom and secured in V position by means of stud bolts 9 in a common way, and 10 represents fly wheels secured to opposite ends of theshaft. Integral with one of the separable upper half boxes 8 is a rearwardly extendin bracket member 11 provided with a lateral y disposed boss 12 that receives the reduced end 18 of a stud 14 dis show posed parallel iiith the crank shaft 5 andavmg-a pulley 15 journaled thereon. 16 represents a spur gear member secured to the Web of the pulley by means of bolt 5,17 and meshing '11 h a drlvin pinion 18 secured to the era 1k shaft. he bracket 11 extends u ward irom the boss 12 at the out side of t c gear member 16, substantially parallel therewiti, and is rovided at its upper end with boss 19 t nt receives the 66 threaded end of a stud 20, upon which is journaled an int irmediate pinion 21 that meshes with the g -ur member 16,-ul1d 22 represents an inwarlly extending horizontal shelf integral with the bracket and having a magneto 23 sec! red thereto, the armature of the magneto curryingn pinion 24 meshing with the intermediate pinion 21.

A shield for'tle gears includes a plate member 25, having inwardly extendin our members 26 where )y it is to a (1 member 27 secured to o posits sides of ths upper end of the bran at member 11 by means of screws 2!, and curving downward around'the'gcar mi lmbel 16 is secured at its lower end to a burger 29 depending from the bracketmembei 11.

By means of this unitar attachment the structure is greatly simpl' ed and rendered compact. l6

Having shown or id described a preferred embodiment of m invention, I do not de- 'sire that it be-con r ed to the specific details of the structure as illustrated, it be understood that chang es may be made inthe 0 form and proportion of ts parts without departing from the i pix-it of my invention.

What I claim as I 1y invention 'and desire to secure by Letters Patent, is: o, v

1. An internal combustion engine includin'g, in combination, in engine frame, a crank shaft journalod in fix 2d bearing members carried by said frame, separable bearing caps coacting with said fir ed members, and a gear earl-yin bracket integral with one of said separab 0 caps.

2. An internal combustion engine including, in combination, a a engine'frame a crank shaft journaled in fix: dbcaringmem rscarried by said frame, we arable bearing caps c'oacting with said fixo member-fiend a gear carrying bracket intc gral with one of said separable caps having a magneto mounted thereon.

8. An internal ooni i'ustion engine including, in combination, an engine frame, a crank shaft journaled in fixed bearing members carried by said frame, separable bearing caps coacting with said fixed members, and a gear carrying bracket integral with one of said separab e a magneto.

4. An internal combustion engine including, in combination, an engine frame, a crank shaft journaled in fixed bearing members carried by said frame, separable bearing caps coacting with said fixed members,

a pinion secured to'said shaft, a bracket member integral with one of said separable caps, a magneto carried by said bracket, and gear means journaled upon said bracket and operatively connecting said p nion with said magneto.

5. An internal combustion engine including, in combination, an engine frame, a

- crank shaft journaled in fixed bearing members carried by said frame, separable bearing members coactin with said fixed mem- I hers, a pinion secure to said shaft, a bracket member integral with one of said separable caps, said bracket having a laterally disposed shelf adapted to receive bearing members, a magneto carried by said bracket, studs secured to said bracket member, a gear member journaled upon one of said studs and engaging with said pinion,'a driving pulley secured to said gear member, an intermediate pinion journaled upon said remaining stud and meshing with said gear member, and a pinion forming part of the magneto mechanism.

6. An attachment for gas engines including a bearing cap having magneto and pulley supporting means. 7. An attachment for gas engines includtions, 21 magneto secured to one of said p0rtions, and a pulley secured to another.

8. An attachment for gas engines including a bearing cap having magneto supp0rt-- ingmeans.

9. An attachment for gas engines including a bearing cap having a supporting portion, and a magneto mounted on said supporting portion.

In testimony whereof I afiix my signature.
